Abstract

PURPOSE: To obtain the titled compound useful as a reagent for introducing a protecting group of an amino group, etc. easily in high yield, by reacting a reaction product obtained from the reaction of phosgene with pyridine with a bisalkoxycarbonylmercury and an alcohol, etc. one after the ether.
CONSTITUTION: Phosgene is reacted with pyridine in an unreactive solvent at -10W-20°C to give chlorocarbonylpyridinium chloride of formulaI, which is then reacted with a compound of the formula Hg(CH2COOR)2 (R is alkyl) at -10W-20°C to afford an α-alkoxyvinyloxycarbonylpyridinium chloride of formula II. The resultant reaction mixture is then reacted with an alcohol or phenol of the formula R1OH (R1 is alcoholic or phenolic residue) at -10W0°Cto give the aimed compound of formula III. The aimed compound of formula III (R1 is benzyl, tert-butyl or trithylsilylethyl group) which has not been easily prepared can be easily obtained. The compound is useful as a reagent for introducing the protecting group into the amino group.
